Conocimientos y tendencias actuales sobre la aspergilosis broncopulmonar alérgica

Introducción: La aspergilosis broncopulmonar alérgica es una enfermedad pulmonar inflamatoria, caracterizada por una reacción de hipersensibilidad a la colonización de la vía aérea por Aspergillus fumigatus en individuos susceptibles, generalmente pacientes con asma y fibrosis quística. Objetivo: Actualizar los conocimientos en el diagnóstico y manejo de la aspergilosis broncopulmonar alérgica. Desarrollo: Se realizó una revisión bibliográfica temática, observacional y retrospectiva, de diciembre de 2019 a julio de 2020. Se accedió a bases de datos como PubMed/MEDLINE, SciElo, ReserchGate, Scopus, ScienceDirect, Redalyc, Latindex, Wed of Science y LILACS, usando los descriptores en Ciencias de la Salud (Aspergillus fumigatus, aspergilosis broncopulmonar alérgica, hipersensibilidad, allergic bronchopulmonary aspergillosis, aspergilose broncopulmonar alérgica, pulmonary aspergillosis, aspergilose pulmonar, hypersensitivity, hipersensibilidade). Se incluyeron artículos escritos en español, inglés o portugués, que informaron sobre la temática relacionada con aspergilosis broncopulmonar alérgica; seleccionados por la lectura del título, el resumen, el texto completo y por la evaluación de las variables (tipos de diseño metodológico, aspectos metodológicos generales propios de cada uno de los diseños encontrados y calidad de la investigación). Con estos criterios, fueron seleccionados 36 artículos nacionales e internacionales que incluyeron artículos originales, revisiones bibliográficas, estudios de intervención, revistas y anuarios estadísticos. Conclusiones: La aspergilosis broncopulmonar alérgica es mucho más frecuente de lo que se suponía, pero con asiduidad se subdiagnostica y el diagnóstico se hace tardíamente, lo que empeora el pronóstico de estos pacientes. Establecer el diagnóstico y tratamiento oportuno ayudará prevenir el desarrollo de serias complicaciones

Endogenous cardiac stem cell activation by insulin-like growth factor-1/hepatocyte growth factor intracoronary injection fosters survival and regeneration of the infarcted pig heart

ObjectivesThe purpose of this study was to test the ability of insulin-like growth factor (IGF)-1/hepatocyte growth factor (HGF) to activate resident endogenous porcine cardiac stem/progenitor cells (epCSCs) and to promote myocardial repair through a clinically applicable intracoronary injection protocol in a pig model of myocardial infarction (MI) relevant to human disease.BackgroundIn rodents, cardiac stem/progenitor cell (CSC) transplantation as well as in situ activation through intramyocardial injection of specific growth factors has been shown to result in myocardial regeneration after acute myocardial infarction (AMI).MethodsAcute MI was induced in pigs by a 60-min percutaneous transluminal coronary angiography left anterior descending artery occlusion. The IGF-1 and HGF were co-administered through the infarct-related artery in a single dose (ranging from 0.5 to 2 μg HGF and 2 to 8 μg IGF-1) 30 min after coronary reperfusion. Pigs were sacrificed 21 days later for dose-response relationship evaluation by immunohistopathology or 2 months later for cardiac function evaluation by cardiac magnetic resonance imaging.ResultsThe IGF-1/HGF activated c-kit positive–CD45 negative epCSCs and increased their myogenic differentiation in vitro. The IGF-1/HGF, in a dose-dependent manner, improved cardiomyocyte survival, and reduced fibrosis and cardiomyocyte reactive hypertrophy. It significantly increased c-kit positive–CD45 negative epCSC number and fostered the generation of new myocardium (myocytes and microvasculature) in infarcted and peri-infarct/border regions at 21 and 60 days after AMI. The IGF-1/HGF reduced infarct size and improved left ventricular function at 2 months after AMI.ConclusionsIn an animal model of AMI relevant to the human disease, intracoronary administration of IGF-1/HGF is a practical and effective strategy to reduce pathological cardiac remodeling, induce myocardial regeneration, and improve ventricular function
